The way we measure the collars also changed, now we measure the collar with the tightening loop fully extended, so it more clearly matches a neck size on a dog.

Training Collars were Black Dog's first ever product, they were designed for training without the harshness and pain of a chain choker.

Nowadays they are generally used more as a security collar because of the non-slip security of a martingale design - the design helps prevent dogs slipping out of their collar.

Careful consideration to design of the collar, components and choice of materials in relation to the size of dog, has enabled us to produce a highly effective Training Collar that is robust and looks great.

Adjustable - to exactly and comfortably fit a dog's neck, and can be adjusted as your dog grows
